"Performance Lab" increased the performance of the website of shoe retailer Birkenstock by more than 2 times

2021: Improving Site Performance

Performance Lab On July 23, 2021, it announced that retailer footwear Birkenstock it had more than doubled the performance of the selling site before the selling season.

Online shoe store Birkenstock was preparing for a big sale. It was expected that the site's attendance would increase fivefold, so the customer had to assess whether the site could cope with the increased load during the peak period.

To solve the problem related to the upcoming load, Birkenstock turned to Performance Lab The specialists of Performance Lab decided to use the developed boomq.io solution itself to create a load testing scenario based on client data from Google Analytics. Two iterations of testing were performed. The first iteration showed that the site is not prepared for an increase in attendance. The caching of the web server was not configured, and the NGINX and DB configurations were suboptimal, so the website could only withstand a threefold increase in traffic, and not a fivefold increase, as expected by the customer.

According to the results of the first tests of load testing, Performance Lab gave the customer detailed recommendations for optimizing the site. When optimization was completed, a second iteration of testing was performed, which showed that an optimized website can withstand a sevenfold increase in traffic. As a result, the customer received a comparative report on the test results, including the complete minimization of critical errors, including the implementation of reducing the response time to 12 seconds. Now the client's site can withstand 700 simultaneous visitors, thus, performance more than doubled (from 300 to 700), although initially the client planned to effectively configure the site while simultaneously logging in 500 customers.

Load testing with Boomq.io has helped our client find flaws in the architecture of their website. The recommendations of Performance Lab specialists have more than doubled the effectiveness of the site, as a result of which the portal has become ready for any marketing campaign in the high sales season. At the end of the project, the customer received a fully configured test scenario, so in the future he can carry out load testing on his own.
